Application August 19, 1927, Serial No. 214,046 Renewed April 7, 1933 5Claims.

My invention relates to improvements in electrical Vaporizers of thehand type for individual use in generating vapors for inhalation in thetreatment of head colds and other head afflictions.

In my co-pending application, Serial No. 188,559, filed May 3rd, 1927,now Patent 1,775,947, issued Sept. 16, 1930, for Electric Vaporizers, Ishow an instrument of this character, and the object of my presentinvention is to adapt the vaporizer to the container in which thecompound to be vaporized is marketed.

In the drawing Figure 1 is a sectional side elevation of my improvementshowing it applied to the bottle or jar in which-one of the standardcompounds is marketed;

Figure 2 is a bottom view of the plate I4, and

Figure 3 is a view of a modification of my improvement.

My invention comprises a sleeve or cap 5 in which a hollow body 6 ismounted so that it may slide up and down in the sleeve The lower end ofthe body is turned outward at l to prevent the body being lifted out ofthe sleeve. The body is made of any suitable material and shape, butpreferably of metal and to the general conformation shown. On the upperend of the body I mount a perforated nozzle 8 adapted to fit the nasalpassage. The nozzle is removably set over the upper end or neck 9 of thebody. Within the body and extending through a wall thereof, I provide atube or housing I0 within which a suitable resistance coil is mounted.The coil is of course insulated with respect to the tube 10 and ispreferably covered with a suitable non heat conducting material exceptas to its lower or exposed end I I. Over the lower end of the coil Imount a cover or cap l2 which is threaded to or pressed over the tube l0. The tube is positioned laterally within the body 6 by the plate 14which is pressed into the lower end of the body or otherwise securedtherein. The plate is perforated at IE to permit the vapors generated tobe drawn through it. A shoulder IS on the tube is drawn into rigidengagement with the body 6 by a suitable switch 11 threaded to the tube.An ordinary electric cord I8 is connected through the switch to theresistance coil II. The compound to be vaporized is carried in the jaror container I8, the same being the jar in which the compound ismarketed and to it the sleeve 5 is threaded.

In operation, my improved vaporizer is mounted on the jar It in themanner just described, and the body 6 is moved up or down in the sleeve5 to set the cap 12 into the compound, preferably about half the depthof the cap. The current is then turned on through the switch I! andquickly brings the cap l2 to a temperature such as will vaporize thecompound that is immediately adjacent to and in contact with the cap.The vapors thus generated are, on inhalation, drawn up 5 through thechamber A of the body 6 and through the nozzle 8. During the act ofinhalation a current of air enters the container l8 through the recessor groove 20 formed in a wall of the body, and thence up through theopenings l5 of the 10 plate ll to the nozzle 8. The chamber A is heatedby the resistance coil II warming the vertical portion of the tube 10.The current of air mentioned is therefore heated in this chamber, andthe vapors are delivered to the afliicted meml5 branes at an eflectivetemperature. By turning the switch I! on and off during the use of myinvention, the vapors can be generated in the volume and at thetemperature preferred.

By shoving the body 6 downward in the sleeve 20 5 and thence upwardly tothe limit of its upward movement, the cap 12 may be dipped into thecompound. This operation will leave the cap coated with a film ofcompound which will be quickly vaporized when the electric current is 25turned on. This arrangement may be said to constitute means fordelivering the compound from the container 18 to the heating element orhot-spot ll.

The resistance coil ll may be made in any de- 30 sired form, either suchas shown in my above co-pending application, or my other co-pendingapplication Serial No. 194,437, filed May 26th, 1927, for ElectricalVaporizers. Or the lower end of the coil ll may terminate in a selfcontained 5 heating element or hot-spot such as shown in my co-pendingapplication Serial No. 212,111, filed August 10th, 1927, for ElectricalVaporizers.

The modification of my invention shown in Figure 3 consists of a handle2| and a heating element or tube 22 such as shown and described in myco-pending application first above mentioned. The tube 22 is providedwith indentations or cups 23 preferably near its upper end.

A sleeve or barrel 24 is dropped over the heating 45 element 22 with thecap or stock 25 resting on the upper end of the heating element. The capis provided with a plurality of perforations 26.

A nozzle 21 sets in the upper end of the barrel 24 and has a groove 28through which a current of 50 air, under certain conditions, enters thebarrel on inhalation.

In operation the heating element is dipped into the compound to bevaporized, preferably when the element is hot. The compound fills thecav- 55 ities 23 so that on extraction oi the heating element, some ofthe compound adheres to it causing vapors to rise therefrom. The barrelM is then dropped over the heating element and the vapors are oninhalation drawn up through the nozzle 21. By closing the holes 26 inthe cap 25 the compound may be placed in the chamber or barrel 24 at apoint above the cap. When thus placed the compound will be vaporized bycontact of the hot upper end of the heating element '22 with the thincap 2|.

What I claim is:

l. A device for generating vapors for inhalation, comprising incombination, a container for containing the compound to be vaporized, aheating element extending from above the compound into the latter, meansfor mounting the heating element on said container including means foradjusting the element in relation to thebottom of the container, andnozzle means through which the vapors generated are drawn.

2. A device for generating vapors for inhalation, comprising incombination, a container for containing the compound to be vaporized, ahollow body adjustably secured on said container and having on one end anozzle for application to the nasal passage, and a heating elementcarried by said body and adjustable thereby relatively to the containerwhereby to generate vapors to be grawn through said body and nozzle oninhala- 3. A device for generating vapors for inhalation, comprising incombination, a container tor containing the compound to be vaporized,including a hollow body, means for heating said compound to generatevapors and adjustable reatively to said body, and a nozzle through whichsaid vapors and a draught of air are drawn upwardly through said body,said current of air being heated as it passes through the body.

4. A device for generating vapors for inhalation, comprising incombination, a container for containing the compound to be vaporized, anelectrical heating element adjustably supported on said containerand-adapted to be dipped into said compound from above the latter, andmeans through which the vapors generated are drawn on inhalation.

5. A treatment appliance of the class described comprising a hollowbody, a heating member movable into the body and suspended in spacedrelation to the same, a medicament heating surface in said body withwhich the heating member is adapted to cooperate to transmit its heat tothe medicament contacting with said surface, and means for conveying theheated vapors to the part to be treated.
